农用残膜对土壤理化性质和作物产量影响的研究

Study on the Effects of Agricultural Residual Film on Soil Physicochemical Properties and Crop Yield

农用残膜会改变土壤的理化性质,进而影响农作物的产量。本文选择玉米、大豆、小麦等农作物作为实验对象来探讨农用残膜对土壤理化性质跟作物产量的具体影响。研究结果表明,将农作物种植在没有处理农用残膜的土壤中跟种植在清除了农用残膜的土壤中,农作物产量是存在较大差异的。对比清除农用残膜的土壤,清除土壤中的农用残膜清除后,农作物的产量能够增加13.79%-24.38%,土壤的理化性质也有较大程度的改善。

Agricultural residue film will change the physical and chemical properties of soil,and then affect the yield of crops.In this paper,corn,soybean,wheat and other crops were selected as experimental objects to explore the specific effects of agri⁃cultural residue film on soil physical and chemical properties and crop yield.The results show that the crop yield varies greatly between the soil without the treatment of agricultural residue film and the soil with the removal of agricultural residue film.Compared with the soil that removes the agricultural residual film,the crop yield can increase 13.79-24.38 and the physical and chemical properties of the soil are improved to a great extent.
